以下是我传递给connection.spot_requests.create()的参数。
{:price=>"1", :image_id=>"ami-63be790a", :groups=>["mcsl-web", "default"], :flavor_id=>"m1.xlarge", :key_name=>"mcsl", :availability_zone=>"us-east-1a", :block_device_mapping=>[{"DeviceName"=>"/dev/sda1", "Ebs.VolumeSize"=>"8", "Ebs.DeleteOnTermination"=>"true"}]}
这是错误：
